This year's Robot Games
are easily an order of magnitude larger and more robust than anyone can remember, thanks to the heroic efforts of SFRSA President David Calkins and his team, working with Exploratorium Technical Curator Larry Shaw & Multimedia Specialist Ron Hipschman & their Engineering & Webcasting task forces. The Exhibits area is greatly expanded with new guests including, for the first time,
several NASA Robotics groups. In addition to the Robot Sumo competition, there are several varieties of new Maze & Obstacle Challenges & many new Demonstrations. Joining the Sumo
competition this year is a new competition event, the Robot "Greyhound Dog Races". Beyond the competitions are the Bots themselves - so many rarely, never before and newly seen machines, (with LEGO Mindstorms filling a hefty percentage), that the Games this year resemble a Robotic
CambrianExplosion. Among the many evolutionary experiments are several new species of robot that would seem to be candidate
"BiomorphicExplorers" of the type that, for example NASA is planning to utilize in
the Robotic Exploration of the Solar System. For instance, one Mindstorms machine nicknamed the "Spanner" demonstrates a gap or chasm crossing ability that on a larger scale could offer an effective solution to fording a
glacial crevace while searching for life on a ice covered world such as Jupiter's
moonEuropa, beneath which ice appearances suggest there may be ocean, geothermally heated & possibly life supporting.

As visitors enter the Exploratorium, they stroll up to the large classrooms whose
entrance house the Robot Games Exhibits
and Competitors Pit areas. In the Pit there are many unusual designs including an AOL CD
Line Follower, a Robot Store
"Flipbot" and the Mindstorms
"Spanner" Biomorphic Explorer candidate. Upon encountering a chasm, the Spanner Bot swings out a panel to bridge the gap, then further swings out a grappling arm which, upon anchoring at an opposite end, operates a hoist to pull itself across the
gap .

Moving on to the Exhibits, visitors are greeted by a poster of the "Hitchicker's Guide to the Galaxy" (and
digital Prozac candidate) "Marvin
the Paranoid Android", followed by a striking Robot Store display of Radio Controlled Battlebots toys
and new Mark Tilden "bugs". The bugs are also Biomorphic Explorer candidates and represent a unique evolutionary branch of robots, as they are analog, not digital, capacitor network charge-based, not microprocessor-based, and utilize nervous nets, not neural nets. Their navigation and obstacle-avoidance abilities are not programmed but rather arise dynamically as emergent behavior by a capacitor network charge state seeking to return to resonance from being disturbed by encountering an obstacle - they are in effect Chaos Fractal Strange Attractor-driven machines. (More information on Mark's designs & machines can be found on the
Solarbotics and B.I.O. Bugs sites).

Moving out into the Competition and Exhibition areas, visitors encounter a Sony Entertainment Robot (ERA) AIBO 210/310 Exhibit and try-out
maze and a new event
that I created called the Sony
AIBO Greyhound Dog Races.
The setup utilizes a laptop running AIBO "Navigator" software to send navigation commands to the robot wirelessly, across a 802.11b Wireless LAN network using an Access Point and pair of Wireless LAN PC cards (one each in the laptop and robot), enabling the operator to serve as
"virtual jockey". A close-up of the
Navigator Control screen, shows live video transmitted from the dog, currently executing behavior routines ("Blow a Kiss", lower right corner), audio clip playback (lower left corner) and other functions such as head-mounted video camera pan/tilt control, leg kick and head moves and general navigation controls.
Major pre-event technical help with the Wireless LAN installation was provided by Software and Games Engineer, the
Godfather of Lemmings, Mike Farren, along with considerable Graphics production help from SFRSA WebBotChick Toni Thompson, both over several very late night marathon sessions in exchange for mass quantities of caffeinated beverages. Further on-site event setup help and moral support was provided by
Space Tourism Promoter and SFRSA Robot Games Über-Volunteer
Sam Coniglio and young robotics prodigy Kyle
Rader, respectively - Thanks heaps, guys!

As show time approaches, the audience bleachers
fill and the Exploratorium's sophisticated mobile webcasting studio goes through final checkout and begins transmitting event
audio clips. Robot Games co-hosts,
TechTV "Screen
Savers" host Leo Laporte and SFRSA President David Calkins, appear at the stacked Mini-Sumo and Sumo rinks to
welcome the crowd. The pair demonstrate Sumo by
assuming the positions, then describe a typical
Mini-Sumo machine, noting that many of today's entrants built their machine in robot-building classes taught both by David at the Exploratorium and by SFRSA Member Zach Radding at his
Cool Stuff Robot Workshop in the
East Bay. Now the hosts officially open the Games. The Sumo competitions begin as each pair of competitors
bow to each other and set their machines to
start. After scurrying about the rink searching for one another, the autonomous robot warriors try to acquire one another as targets, sometimes invoking various forms of camouflage, subterfuge, or disablement strategies, utilizing boundary detection routines to stay within the rink, and engaging in a fierce battle to push each other out of the rink. While a number of contests end in draws or timeouts, others provide the classic Sumo experience, among the more memorable being the bout between
Rebel vs. Thunder, and
GV1 vs. Hedgewig, while to stare at Tinkerbell's opponent is to confront the face of
Mecha-Terror. Another bout, involving a disablement strategy of blinding the opponent with a
flashlight, amazingly, does
not succeed. Among bouts that follow,
Andrew Miller's Hurricane
escorts his opponent to the beyond, while Hedgewig shows Thunder the meaning of defeat.

Behind the scenes, Exploratorium Technical Curator, physicist Larry Shaw, "Godfather" of the SFRSA, is
working the controls of the webcasting studio under the watchful eye of a Star Wars Storm
Trooper, perhaps evaluating the scene in preparation for ILM's pending relocation to the
Presidio across the street from the Exploratorium. During a break between events, Larry steps out to grab a few photos, seemingly quite
pleased with how far his mecha-progeny have evolved over the last several years of the SFRSA at the Exploratorium. Thereafter the Storm Trooper
joins his friend, famous Star Wars Robot actor, R2D2, for whom the greatest challenge recently has been autographs.

Following the Sumo matches the new AIBO Greyhound Dog Races get underway. After several shakeout trial runs, the main race between the SFRSA SIG AIBO Club's K9 and Sony Entertainment Robot America (ERA)'s entry is about to begin. The Robo-hounds jockey to the starting line, a countdown of 3-2-1 is heard, and they're off! Sony ERA takes an
early lead but as the dogs round the first turn, they bump into one another and struggle with
entanglement, reminiscent of the chariot race battle in the movie Ben Hur. Rounding the bend and headed into the home stretch, K9 manages to break free and
pull ahead. Rounding the final turn back to the starting point, K9 ends up
beating Sony ERA by several lengths. The entire race, caught on video, lasts nearly 3
minutes . More races ensue, and amazingly, K9, seemingly "in the zone", wins every race that follows, beating Sony 3 times, until mysteriously, Sony's machine stops working altogether. Despite intense efforts by the ERA team to reboot the system, the condition persists, causing one wag to observe that sometimes this same phenomena occurs in Japanese Robot Sumo, where it is described by a word that in English means the machine has entered a state of "having lost the will to survive". With these latest victories, it is difficult to
assess just how much the presence of the Tech TV Digital Cable and Internet Webcast TV cameras, broadcasting live to a potentially global audience, have contributed towards nudging AIBO K9, or at least his notoriety, to the brink of Superstardom. Never one to miss a photo opportunity however, after the final race K9 is wrapped in a victory cloak and taken to the Winners Circle, where he receives his Grand Prize Trophy, a traditional Japanese Samurai Warrior Kabuto Helmet. Perhaps the secret of K9's success is written in Japanese across
my racing headband, which translated into English reads,
"Sure To Win".

Following the Dog Races, a set of really impressive and even rare Demonstration Events start in the Games main staging area, beginning with a wireless infrared controlled pair of
Mindstorms Line Following Bots, followed by a pair of
NASA USFIRST Competition Robots. Next comes the march of the Hexapod Walkers, featuring SFRSA member, robot artist/neurologist
John Zeissig's Fuzz Knuckles, joined by
Psyclops roboticist
Nicholas Donaldson's Ziggy and Flik. Proceeding to display their Obstacle Course navigational skills, Fuzz Knuckles starts off by demonstrating a unique Artificial Intelligence solution to the problem - after assessing the difficulty of the situation as bordering on the ridiculous, Fuzz Knuckles, in his own inimical style, effects a "Later, Dude" maneuver by simply turning around and
avoiding the obstacle all together
.
Ziggy, however, transporting a tiny driver who is the very expression of Alien Intelligence, is unstoppable in his
fearless assault on the debris-strewn landscape
. Thinking we have just witnessed the highlight of the Games, the audience is not prepared for the surprise finale trick Ziggy has stashed up his end-effector - placed in front of a never-before-seen type of obstacle course, Ziggy has to traverse a series of delicately suspended horizontal beams without knocking any loose from their supporting posts. Once again Ziggy's Obstacle Avoidance routines deftly carry him over the beams with all the precision and finesse of a
6-legged Ballet dancer, eliciting gasps of amazement from everyone, including the announcers. Ziggy's partner
Flik, an impressive dual RCX Mindstorms creation, turns in a similar performance. These Biomimetic-inspired insect-like machines, with their ability to climb over obstacle courses strewn with more and varied rubble
than is typically seen in the Mars Pathfinder Sojourner Rover
photographs suggests
such Hexapods as excellent prospects for Biomorphic Explorers.

After the Hexapod show, a final series of Demonstration events begins adjacent the Obstacle Course. A miniature
tractor-tread upright Bot, resembling the movie "Short Circuit's" robot actor "Johnny 5", entertains the crowd by performing whirling dervish-like pirouettes. Next a Mindstorms Bot, featuring a
dual-axis Cartesian coordinate drive
train, demonstrates right-angular direction change without turning, while navigating an impromptu maze.
Springy and Bugsy follow with an appearance, delighting the crowd with a series of madcap Marx Brothers-like antics.

Next, Seattle Robotics Society (SRS ) rolls out "Hors D'oeuvres Bot", who seems to cater to a psychological archetype deep within the psyche of the male roboticist, known as "Robot Engineer Man". In Robot Engineer Man's (REM) never ending attempt to inquire of the Ladies as to the possibility of
"a Date", (and to get a Robot to do it for him), REM's Hors D'oeuvres Bot, an Autonomous Date Seeking Robot, uses sophisticated Sonar and Heat-Seeking technology at cocktail parties to locate and acquire potential Date candidates. Once a target is acquired, Hors D'oeuvres Bot rolls up to the hapless female, and, bearing a plate of
Hors D'oeuvres, begins engaging in Sensitive Chit Chat ("Oh those Humans, they're all alike"). It sounds like this is just the Bot for SFRSA President and Robot Games co-host David Calkins, who next encounters
Obstacle Avoidance Bot, described as being much like the women in Dave's life - they come up, touch him, turn around and go
away.

Following these machines, who give new meaning to the phrase "Human Partner Robots", are some remarkably unique mechanisms. There appears a people seeking, infrared beacon following,
dual AOL CD ROM wheeled, self-balancing
Bot. Next on the scene is an undulating Snake Bot
. Following the mecha-reptile, an amazing pantograph-based, lateral inch (more like foot) worm Bot
expands and contracts
it's way horizontally across the floor, then, after a few adjustments, further surprises the audience by transforming itself a Rope Climber, and
expands and contracts
it's way vertically along a Rope. Next comes a Tank-like Mindstorms Maze Bot, followed by the return of Ziggy, who has re-purposed his Obstacle Course algorithms to present a rocking
Dance Number. Ending the Demonstrations is a Star Wars inspired
Cleanup Droid. Then Robot Games 2001 itself ends with a Grand Finale Demo Bot
Melee.

All-in-all, an impressive array of robotic technologies - and a pretty neat way to spend a Sunday
afternoon (be sure and check back at the Exploratorium's Robot Games webcast
site, where, when resources permit, the Exploratorium may post a
"Best of" Robot Games Webcast Archive). Kudos to the Competitors, Exhibitors and Event
Organizers!
